Abstract

The growing global interest in edible insects as a sustainable protein source has positioned them as a promising solution to food security challenges. In Mexico, entomophagy is deeply embedded in cultural traditions, particularly in Oaxaca, where grasshoppers, leafcutter ants, and red agave worms form an integral part of the region's intangible heritage. This study conducted a bibliometric analysis of global research on edible insects (2009-2023) using Scopus and tools such as VOSviewer and Bibliometrix to analyze 218 publications. The analysis highlighted research trends, influential authors, and key themes, including nutrition, biosafety, and sustainability. To complement the bibliometric study, an exploratory analysis of edible insect commercialization in Oaxaca was conducted, focusing on virtual platforms and local markets. The findings reveal consistent global growth in edible insect research, with Mexico contributing six publications between 2020 and 2023. Despite advancements in safety standards and regulatory frameworks globally, Mexico still lacks formal sanitary controls and regulations for insect-based products. Nevertheless, its diverse commercialization efforts and rich cultural heritage, particularly in Oaxaca, showcase its potential to bridge tradition and innovation. This study highlights the urgent need for regulatory frameworks and research capacity to ensure safety, preserve cultural identity, and sustainably expand Mexico's edible insect market.
